Parser phase one constructor

Takes the player interface object as a parameter. This interface is used by the parser for reporting parse errors and for getting values of the content control attributes. It is also passed to the created presentation object.

Parameters

MSmilPlayer * aPlayer

ParseColor(const TDesC &, TBool &)

IMPORT_C TRgb	ParseColor	(	const TDesC &	aString,
			TBool &	aTransparent
		)	[static]

Parses a CSS2 style color value ("red", "green", "#ffcc44", ...) The aTransparent flag is set if the parsing fails

Parameters

const TDesC & aString
TBool & aTransparent

ParseL(const TDesC &, const TDesC &)

IMPORT_C CSmilPresentation *	ParseL	(	const TDesC &	aSmil,
			const TDesC &	aBaseUrl
		)

Parses the given SMIL source, constructing the presentation object. The given base URL is used for resolving the URLs in the presentation.

Verbose parse error messages are available through the MSmilPlayer interface.

Parameters

const TDesC & aSmil
const TDesC & aBaseUrl

ParseL(const CMDXMLDocument *, const TDesC &)

IMPORT_C CSmilPresentation *	ParseL	(	const CMDXMLDocument *	aSmilDoc,
			const TDesC &	aBaseUrl
		)

Parses the given SMIL document, constructing the presentation object. The given base URL is used for resolving the URLs in the presentation.

Parameters

const CMDXMLDocument * aSmilDoc
const TDesC & aBaseUrl

ParseTimeListL(const TDesC &, TBool)

void	ParseTimeListL	(	const TDesC &	aString,
			TBool	aBegin
		)	[private]

Parameters

const TDesC & aString
TBool aBegin

SetMaxDownUpScaling(TReal32, TReal32)

IMPORT_C void	SetMaxDownUpScaling	(	TReal32	aDown,
			TReal32	aUp
		)

Enables the layout scaling. This functionality shrinks the layout so that it fits the screensize while maintaining the original aspect ratio. Images and other media is not scaled unless scaling is is enabled by the fit attribute of the region element of the source document.
